The MicroStrain 3DM-GQ7-GNSS/INS is an all-in-one navigation solution featuring centimeter-level position accuracy. It is our first dual-antenna, RTK enabled INS designed for outstanding performance, even in unpredictable conditions. It is equipped with dual multiband GNSS receivers, low noise and low drift MEMS inertial sensors, and a robust adaptive Kalman filter.

 

When paired with our 3DM-RTK Modem and SensorCloud RTK corrections service, the 3DM-GQ7-GNSS/INS is the best single-vendor RTK navigation solution available.

Sensor

  • Up to 1 cm + 1 ppm positional accuracy with RTK

  • Multi-frequency GNSS receivers provide 1.2m single point L1/L2 position accuracy
  • Multi-constellation receivers with 184 tracking channels each allow for rapid signal acquisition and robust signal tracking in challenging GNSS environments
  • Dual GNSS antenna heading with 0.2° heading accuracy that is immune to magnetic disturbances
  • Tactical grade IMU with <2°/hr bias instability provides exceptional position accuracy during GNSS outages
  • 0.05° pitch/roll accuracy

Operation

  • Accepts standard RTCM real-time kinematic (RTK) corrections

  • Adjustable sampling rates up to 1KHz
  • 34 state auto-adaptive EKF
  • Independently configurable IMU, GNSS, EKF outputs
  • Forward compatible MIP Protocol optimizes bandwidth
  • SensorConnect software for configuration, control, display, and logging
  • MSCL open source API for easy integration

Package

  • Anodized Aluminum

  • Precision alignment features
  • Highly compact and low profile
    • 76 mm x 68.6 mm x 13.3 mm
    • 78 grams
  • USB and RS-232 interfaces
  • –40 to +85°C operating temperature range
